A collection of engineering studies demonstrating how KADMOS turns first-principles physics and code compliance into practical, licensable reactor systems.
Code Based Design for RPV’s
ASME-compliant, physics-driven pressure vessel designs engineered for long-term safety, licensability, and ultra-low failure risk.
Code Based Design for RPV’s
We bring a practical, code-based approach to designing ultrareliable pressure vessels for advanced nuclear systems, addressing the fundamental challenge of managing the immense forces created by very large diameters and high internal pressures.
Using ASME Section III, Class 1 rules, NRC 10 CFR 50.55a requirements, and advanced stress analysis grounded in first-principles physics, we develop closure concepts that are safe, repeatable, operable, and fully licensable.
The KADMOS reactor pressure vessel embodies this rigor, combining massive safety margins, world-class nuclear manufacturing quality, and cost-effective innovation to deliver a pressure boundary designed for 60 years of service with an exceptionally low probability of failure, providing a robust and enduring foundation for the customers.
Decay Heat Removal
Passive, pump-free heat removal using natural physics to safely manage post-shutdown reactor heat for weeks.
Decay Heat Removal
Using first-principles physics and code-aligned assumptions, we determine how the decay heat removal system is designed to safely absorb and release post-shutdown reactor heat without boiling, pumps, or operator action for weeks.
Our analysis goes beyond rules of thumb, clearly demonstrating how pool size, geometry, and natural heat transfer set real safety margins.
The result is a simple, robust, and a licensable solution that delivers dependable heat removal using physics you can trust.
Primary Coolant Pump Analysis
Comparison of pump architectures to identify safer, simpler, leak-free cooling solutions for modern reactors.
Comparative Analysis of Primary Reactor Coolant Pump Architectures
Choosing the right reactor coolant pump is critical to the safety, cost, and performance of a pump-assisted natural circulation reactor.
Unlike traditional mechanical-seal pumps, which require frequent seal replacements and introduce leakage and safety risks, sealless pumps provide a fully hermetic design that eliminates leak paths, simplifies safety analysis, and removes the need for complex support systems.
Reactivity Insertion Accident (RIA)
Inherently safe reactor behavior that naturally stabilizes power without active shutdown systems.
Reactivity Insertion Accident
The KADMOS reactor redefines nuclear safety by achieving true inherent, walk-away protection system.
The reactor represents a major leap in nuclear safety by proving it can naturally stabilize itself during a Reactivity Insertion Accident (RIA). By utilizing passive negative feedbacks, the reactor automatically neutralizes sudden power spikes: as the fuel and water heat up, the physics of the system naturally drives the power back down to a safe, steady level.
The analysis carried out shows that even under extreme test conditions, the reactor’s internal temperatures stay well within safe limits, and its natural circulation cooling remains robust and uninterrupted.
This "hold-without-scram" capability demonstrates that the KADMOS design is inherently resilient, providing a level of safety that relies on the laws of nature rather than mechanical intervention.By eliminating reliance on active shutdown systems during the most demanding transients,
KADMOS delivers unmatched passive, physics-driven resilience paving the way for advanced nuclear power that is cleaner, more affordable, and profoundly safer than ever before.
Cost Basis
Modular, factory-built reactor designs that cut construction time and reduce costs by up to 40%.
Cost Basis
Kadmos Energy Services is overcoming the high upfront costs of traditional large reactors by completely redesigning the nuclear delivery model, not just shrinking the technology.
Their approach focuses on standardized, factory-built modules that dramatically reduce on-site construction time and labor costs, leading to a potential 40% cost reduction from the first unit to subsequent builds through "learning-by-doing" and economies of multiple units.
Furthermore, they are leveraging simplified designs with advanced passive safety systems that rely on natural forces, which minimizes complex, expensive active safety components and further cuts capital expenditure and risk.
This innovative, modular approach is designed to provide cost predictability and financial scalability, making nuclear energy accessible and competitive for a wider range of customers, from utilities to industrial clients.
